3 Reasons to Use a Deep Wellpoint Dewatering System

About Me

Are you looking for somewhere that you can hire construction equipment for your next project? Maybe you are wondering whether it makes more sense to buy what you need rather than paying hiring fees for a long-term project. Whatever type of construction work you need to have completed having the right equipment on hand is key to the successful completion of the project. This website will guide you through the process of choosing and obtaining that equipment. You can find articles here with advice on when buying equipment is better than hiring, and when hiring makes more financial sense for your business.

If you've decided to use a wellpoint system to pump water out of your construction site, you can use a standard configuration. This gives you a range of small wells connected to a pump that work together to dewater the area.

However, there are times when a deep system is a better option. This system can also deploy multiple wells; however, each well typically has its own pump. When should you consider using a deep wellpoint solution?

1. You Have Deeper Drawdown Needs

Standard wellpoint systems are effective. Each well works as part of a collective whole to draw water out of an area to make it safe and workable.

However, a standard configuration won't work in every scenario. For example, you may have problems dewatering ground if the water runs deep inside it. A standard setup may not be able to reach down deep enough to tap into the water you need to remove.

Deep wellpoint systems can typically go further into the ground. Their independent pumping mechanism helps them pull out more water. This makes them the best option for sites that have deeper draw-down needs.

2. You're Working on Difficult Ground

Standard wellpoint systems work well in some soils. Typically, they work best in silty or some sandy conditions. They don't, however, always work well in highly permeable ground or in ground that contains a lot of gravel.

If the ground you're going to work on isn't wholly suited to a standard system, then a deep wellpoint setup will be a better option. These systems work better in difficult ground conditions. They go in deeper and are more stable.

3. You Have Access Problems

If you install a regular wellpoint system, then you dot a series of small wells around the perimeter of your site. While this might not affect your working conditions on some jobs, it can pose problems on others.

If you don't have easy access, then the wells may get in the way of your work. You may have to work around them and then move them periodically to clear access points.

While you'll often set up multiple deep wells, you may not need as many wells as you would in a standard configuration. Each deep well can do more work. In some cases, you may be able to get away with just one or two wells around the site. This keeps your access and working areas clearer.
